Formamide decomposes at high temperature. if 0.186 mol of formamide (hconh2) dissociates in a 2.16 l flask at 400 k, what are the concentrations of all species present at equilibrium at 400 k? (hint: calculate concentrations first) (b) what is the total pressure in the container at equilibrium?

The modern periodic table has groups.
